The object of my invention is to provide a novel wheelbarrow having novel means for easily dumping the wheelbarrow when a load is to be discharged, and to provide the novel combination 5 and arrangement of parts illustrated. I attain these and other objects of my invention by the mechanism illustrated in -the accompanying drawings, in which- Figure 1 is a-side elevation of my invention in 10 position for carrying a load;

Fig. 2 is a side elevation of my invention in dumping position, a portion of the handles being broken away for lack of space;

Fig. 3 is a top plan view of the invention when bar 2, aflixed to and bracing bars I, legs 3 on 25 bars I, a wheel 4 and axle 5, mounted in the forward ends of bars I. The barrow I has brace bars 6 afl'lxed to its forward end, said brace bars being pivotally mounted on the axle 5. At the rear end of the barrow is a bracket 8 aflixed to 30 its underside and carrying a bolt 9 which is slidable in the slot 29 of the elevating or dumping bar 28.

Aflixed to the rear end of barrow I, I provide a latch bar ill, terminating in the hook end ll.

35 I provide a cross bar [2, mounted in the ends of barrow supporting bars l, as shown in Fig. 3.

Mounted on cross bar I2 is a sleeve l3, on which is mounted or integrally formed the latch H,

which. is detachably engageable with the book end ll of bar I0. I provide a suitable length of cable l operatively connecting latch l4 with.

the manually operated trigger l6. Trigger I6 is pivotally mounted at I! on one of the bars 20 as shown in Fig. 4. I provide any suitable latch 45 spring secured to latch l4 and releasably holding said latch in operative engagement and the level of latch bar III, as shown in Fig. 1.

As shown in Fig. 4 I provide a cross brace l9,

aflixed to and bracing the barrow lift bars 26.

50 The forward ends of bars 20 are braced by a cross bar 2|, to which are aflixed the barrow dumping members, which may be the plates 22, (or

suitably mounted rollers occupying a similar position and performing a similar function).

55 Plates 22 are'fastened to bars 2| by suitable means such as bolts 23. Fastened to bar 2| by suitable means, such as plate 25, is a, bracket 24 which has slightly upturned flanges or ears 26. A barrow elevating bar 28 is pivotally mounted on the ears 26 by the pivot or bolt member 21. Bar 5 28 has a longitudinal slot 29, as shown in Fig. 4,

slidably attaching the bar 28 to the bracket 8 by the bolt 9, as shown in Fig. 2.

In ordinary use the barrow I is latched in horizontal position on the supporting bars I by the-latch H which engages the latch bar I, as shown in Fig. 1. When it is desired to dump the load in the barrow the operator presses on the trigger l6, thus releasing the latch M from its engagement with the latch bar Ill and pressng down on the handles H of the barrow lift bars 20. Those bars are tilted so that the handles are near the ground and the forward ends of the bars in raised position. The plates 22 press on the bottom of the barrow and swing it upwardly to an approximately vertical and dumping position, and the bar 28 pivots on the upturned cars 26 orbracket 24. The bolt 9 on bracket 8 engaging the slotted portion 2.9 of the link or dumping bar 29 permits the barrow to swing to the extreme and nearly vertical dumping position shown in Fig. 2 of the drawings. The supporting bars 26 are pivotally supported on the axle 5 so as to permit the necessary swinging movement of the barrow to move from an ap- 30 proximately horizontal to an approximately vertical dumping position.

What I claim is:-

1. In a dumping wheelbarrow of the type described, the combination of a wheel and axle, barrow supporting bars and legs, barrow, brace bars aflixed to the barrow and pivotally mounted on the axle, and a dumping mechanism comprising barrow lift bars pivotally mounted on the barrow supporting bars, barrow dumping membars contacting with the bottom of the barrow and carried by the barrow, lift bars for pressing on the bottom of the barrow to raise the rear end thereof to a dumping position, a bracket carried by the barrow lift bars, a link bar pivotally connected to said bracket, a bracket on the barrow, and a slidable connection between said bracket and said link bar.

2. In a dumping wheelbarrow of the type described, the combination of a wheel and axle, barrow supporting bars and legs, barrow, brace bars aflixed to the barrow and pivotally mounted on the axle, and a dumping mechanism comprising barrow lift bars pivotally mounted on the barrow supporting bars, a latch releasably aosmaa latching the barrow in loading position, a cross in a normal horizontal position. barrow dumpbar on the barrow lift bars, curved plates mounted on said cross bar and contacting with the bot tom of the barrow for raising same to a dumping position, a bracket carried by the barrow liit bars, a link bar pivotally connected to said bracket, a second bracket on the barrow, and a slidable connection between said bracket and said link bar.

3. A dumping wheelbarrow having a barrow and conventional barrow supporting .bars, means for pivotally mounting the forward end of the barrow, a latch releasably latching the barrow ing means engaging the bottom of the barrow and mounted on the forward end of the barrow liit bars to raise the rear end of the barrow to a dumping position when the handles of the lift bar are depressed, a bracket carried by the barrow 1m bars, a link bar pivotally connected to said bracket, a bracket on the wheelbarrow the link bar having a longitudinal slide at it's forward end, and a slidable connection between said 1
